MODULE SUMMARY

Functions for Set Manipulation

DESCRIPTION

Sets are collections of elements with no duplicate elements.
The representation of a set is not defined.

This module provides exactly the same interface as the module
ordsets but with a defined representation. One difference is
that while this module considers two elements as different if they
do not match (=:=), ordsets considers two elements as
different if and only if they do not compare equal (==).
